/in Grinding media balls /by Sara WuCr25 high chromium cast iron grinding ball, the research is, by the customer China, Electrical Machinery, head office orders, according to, the United States FW proposed, high chromium, grinding ball, technology, conditions, see table 1
Development and application of Cr25 high chromium grinding ball (1)
/in Grinding media balls /by Sara WuSun Tingxiang, Li Maohua, China Building Materials Equipment Corporation (100831) High chromium cast iron grinding ball is widely used in building materials, metallurgy, mining, electric power, and other industries. After 20 years of development, we have basically finished grinding ball, more salary for material and some products have been able to earn 1:3 foreign exchange. […]
Study on the heat treatment process of high chrome cast iron (2)
/in Castings /by Sara WuAlthough high chromium cast iron has good hardenability, high chromium cast iron contains a large amount of chromium, making its thermal conductivity worse. When the cooling rate is high, the steep thermal gradient is easily produced in the casting. Then at different parts of the casting, the phase transition occurs at different times. Also, the […]
Study on the heat treatment process of high chromium cast iron (1)
/in Castings /by Sara WuAbstract: High Chromium cast iron is a kind of excellent wear-resistant material; it not only has good wear resistance but also has a specific camber and toughness; electric Power and other industries have been widely used and achieved significant economic benefits.
High-chromium Cast Ball Heat Treatment Process Research (2)
/in Grinding media balls, Heat Treatment Process /by Sara WuHeat treatment process: It is difficult to quench the wear resistant cast ball, mainly because the quenching requires martensite, and the cooling rate must be higher than the critical cooling rate (VK). During quenching, how can martensite be obtained and the effect of stress reduced? This is a major problem in the quenching process. To […]
